[SCSI] zfcp: fix deadlock between wq triggered port scan and ERP

Waiting for the ERP to be finished in a task running in the global
kernel work-queue is a bad idea, especially if the ERP needs to run
another job in this work-queue before it can finish. -> deadlock.

This patch removes the necessity to wait for a finished ERP from the
scan task and moves the job scheduling to the end of the ERP.
